Climate change is one of the most serious public health challenges we face. Warmer temperatures can enhance the conditions for lethal air pollutants and increase the risk of unhealthy air. In Montana, warmer temperatures, drier conditions, and changes in precipitation are contributing to longer and more intense wildfire seasons, in turn producing dangerous particulate pollution. Climate change is also creating additional strains on those with pollen allergies by way of longer allergy seasons and more potent and numerous airborne allergens. Vulnerable populations across Montana, including children, seniors, low-income communities, and those with chronic diseases, disproportionately bear the health impacts of climate change.
